5.1 Commissioning 1. Filling the system with water 1. Connect the appliance to the main power supply. Due to low pressure, error code "Err HJ-09" will appear on the user interface and the status indicator light will be red. 2. Open all radiator valves. 3. Set all isolating valves to closed position. 4. Measure the system water height. h System charge pressure 0.8bar 0.9bar 1.0bar 1.1bar 1.2bar 1.3bar 1.4bar 1.5bar Up to 6m 7m 8m 9m 10m 11m 12m 13m 4 Configuration & Commissioning - Internal use only
5.1 Commissioning 1. Filling the system with water 5. Slowly turn the filling valve to open position until pressure reaches a value around 0.8 bar for system heights up to 6 meters. For longer system heights, use the table on the previous slide to determine filling pressure. Filling operation should be done slowly. When pressure exceeds 0.8 bar, error code will disappear and the status indicator light will turn to blue. Close the filling valve. The system pressure value can be monitored from the user interface. 6. Make sure the automatic air vent valves located on the pump and heat exchanger are opened. Vent the air from the installation with the manual air vent screws on the radiators. Make sure screws are tightened after venting. 7. If after the venting the pressure decreases below 0.8 bar, refill with water until the pressure reaches 0.8 bar again. 8. Check for leakages. 5 Configuration & Commissioning - Internal use only
5.1 Commissioning 2. Converting for use with a different type of gas To convert the system to be used with a different type of gas: Open the front cover of the unit. To set natural gas, adjust the screw on the gas valve to 1 position. To set LPG, adjust the screw to 2 position. Mount the front cover, connect the appliance to the main power supply. Change setting C00 [0= NG, 1 LPG] 6 Configuration & Commissioning - Internal use only
5.1 Commissioning 3. Filling the condensate trap Method 1: Fill the condensate trap by pouring 0.2 litres of water from the boiler flue outlet. Method 2: Take out the condensate trap.
